Dr Kat Arney, of Cancer Research UK, said more needed to be done to improve the way cancer was both spotted and treated.

She said: "We would encourage people to know what's normal for them and to discuss any symptoms that are new, and happen on most days, with their GP.

"And if symptoms persist, to keep going back to their doctor. It may not be cancer, but if it is then it's vital to start treatment as soon as possible."

To celebrate the first anniversary of her treatment ending, Mrs Greaves is holding an event for Cancer Research UK's Big BBQ Weekend.

She said: "I have to pay Cancer Research back because they helped to save my life because it was their site I looked at.

"I'm going to have beer and a sausage with some onions but no ketchup and no bread.

"It takes me a good 20 to 30 minutes to eat a sausage.

"This is the first time I've celebrated being cancer-free.

"I refused to do it last year when I got the all-clear in the October because I couldn't even drink water.

Husband Damian said couldn't put into words how proud he was of his "amazing wife".

"After the worst-ever year and a half my wife has suffered with this terrible disease, it completely baffles me how she has found the strength and courage to smash this cancer's butt and raise money for charity."
